Brittleness and Toughening of Ceramics

Abstract

Improving the brittleness of ceramic materials has long been a problem of concern to ceramists. Fiber-reinforcing and zirconia phase transformation toughening have been proven to be effective approaches in practice for improving the brittleness as well as the strength of ceramics. This paper will briefly discuss some problems in the study of the above two approaches. The importance of chemical compatibility between fiber and matrix is pointed out in the study of fiber-reinforced ceramic composite materials; the matches of the two in thermal expansion and elastic modulus can not be neglected either, and the moderate bonding of the two boundary surfaces is considered appropriate.
